Seongsu hair salon in Seoul: men's root perm for crown volume at

In short

Toni&Guy Seongsu is a hair salon in Seongsu, Seoul, spread over the 2nd and 3rd floors a 5-minute walk from Ttukseom Station. A boyfriend with thin, flat hair got a men's root perm and cut there in 1 hour 20 minutes, and the crown volume came back, cutting down his daily blow-drying time. One designer handled everything from consultation to cut and neutralization, so Toni&Guy Seongsu is worth a look if you want a men's perm in Seongsu.

For anyone looking for a Seongsu hair salon, I want to recommend Toni&Guy Seongsu today. I went this time to get my boyfriend's hair done, and I was so happy with everything from the location to the atmosphere to the actual result that I have to recommend it if you're hunting for a hair salon in Seongsu.

Where is Toni&Guy Seongsu, and what are the hours?

Exterior of Toni&Guy Seongsu near Ttukseom Station

Toni&Guy is near Ttukseom and Seongsu! It's just 5 minutes from Ttukseom Station, genuinely close to the station, so it's perfect for making plans in Seongsu-dong after getting your hair done. It also seems great for before or after a date.

The salon is closed every Monday, and open Tuesday to Friday from 11am to 8pm, and Saturday to Sunday from 10am to 7pm. Since it opens early, it's convenient if you have plans in Seongsu. Parking is difficult on-site, so I'd recommend using a nearby public parking lot. It's a popular salon, so you absolutely need to book through Naver Reservation before visiting~!

Inside the 2nd and 3rd floors: the consultation at Toni&Guy Seongsu

Neatly organized salon interior

Toni&Guy is split across the 2nd and 3rd floors, so it's not a one-person salon, which felt reassuring, and the neatly organized interior caught my eye right away! We had one designer handle everything. When my boyfriend mentioned the hair concerns he'd always had, she listened calmly and recommended a style suited to his situation, which I really liked.

Salon seating area during a consultation

The salon was clean and the consultation felt relaxed, so even as someone just tagging along, the waiting atmosphere wasn't stressful at all.

Preparing for the root perm treatment

When my boyfriend said his hair is usually thin and lacks volume, the designer recommended a root perm. We mentioned various concerns, and she picked up on them right away and tailored her recommendation, which I really appreciated.

Coffee and snacks served while waiting

The whole process took about 1 hour 20 minutes, and they brought us coffee and snacks while we waited, so it never felt boring. The seats were comfortable too, so time flew by. All the staff were friendly, making it a very low-pressure salon!

Designer personally handling the perm neutralization

The designer herself carefully handled the neutralization and every other step of the perm~! Sometimes other staff, not the designer you booked with, end up doing the actual work at other salons, but at Toni&Guy the designer thoroughly took care of every single step~!

Trimming the cut before and after the perm

She also went over the cut carefully both before and after the perm, so the result looked even cleaner! You could really feel how meticulous she was even watching from the side! My boyfriend said he was satisfied with how carefully both the cut and the perm were handled.

The root perm result: crown volume up, blow-drying time down

Thanks to the perm she recommended, my boyfriend's usual problem of his hair falling flat got solved!! Before, his volume would die down quickly every day so he used to style it with a dryer often, but these days his styling time has dropped a lot~!

The root perm holding up during a trip to Japan

He happened to get this done right before a trip to Japan that same week, and since his hair turned out so neat, he ended up taking a ton of photos on the trip. Even I could tell his hair looked noticeably cleaner and had just the right amount of volume without going overboard. I heard she's also great with women's hair, not just men's, so I'm planning to visit myself next time! If you're thinking about a hairstyle change in Seongsu, I'd recommend Toni&Guy Seongsu for how carefully they handle everything from consultation onward.
